Thislinvention' relates to markers :formarking playing fields with linesof limefor'similar: mate-" rial and has for the primary object the provision of an efiicient, inexpensive'fandportable device, of the above stated character. whichawill discharge'the marking materialuniformly on the playing field and Within a selected pathand 1 which will be easy to handle and guide and which illustrating a playing field marker constructed in accordance with my invention.

Figure 2 is a fragmentary longitudinal'sectional view taken on the line 2-2 of Figure .1 showing the means of agitating the marking material within the hopper and its connection with the supporting wheel.

Figure 3 is a fragmentary sectional view show-.

ing a control gate or valve for the discharge spout of the device.

Figure 4 is an end View showing the door on the mouth of the hopper. v Referring in detail to the drawings, the numeral 5 indicates an elongated hopper which has one end rounded and the opposite end fully open to permit line marking material to be easily placed in the hopper and is normally closed by a door 6. The door 6 may be of the flanged type and hinged on the hopper, as shown at l, depending on the flanges contacting the walls of the hopper to retain the door or cover in a closed position. A suitable finger piece 8 is provided on the cover or door to aid in opening and closing the latter. v

A suitable handle 9' is secured on the top of the hopper for carrying the same from one place to another. A bail or handle W is fixed on 011-.

- posite sides of the hopper adjacent the mouthso that aperson can easily operatethe device in making lines on a playing field.

The hopper 5 adjacent the rounded end and in one side thereof is provided with a comparatively large opening ll normally closed bya re movable plate l2. from the hopper permits an agitator I3'-,to be arranged in the hopper for, the purpose of keep- The plate l2 being removable 1 gperipheryto receive tufts of bristles 34.

' bristles arepreferably constructed of metal or ing; the marking materialfltherein thoroughly agitated.w;1.,:: 1 I v 1'I-'he-lower" wall. ofthe hopper adjacent the roundedgend is provided with a discharge slot 13 directly under the agitator andcarried by the hopper and underlying the discharge. .Slot i3 is a *dischar'gedi spout M of a cross sectionalpshape the ground.

Agate valvev l5yuis pivotally mounted in the spout .,-i4; and is movable relative to the slot 13 for ;controlling; the flow of marking. material 3 through the spoutfrom. the discharge slot l3.

An operating rod 16 is connected to the gate valve i5 and is slidably mounted in a suitable has feed threads l8 and meshing therewith is a knurled feed nut l9. The feed nut I9 is received within anotch' 20. provided inv the Wall of the hopper so that by rotating the feed nut in opposite directions the gate l5 may be moved relative to the discharge slot 13 for varying "the amount of material flowing therethrough.

sleeve is a shaft or axle 22 which: extends out of the hopper by way of an opening provided inythe V plate I2 and which provides amounting for the sleeve. Mounted on the axle to one side of the hopper is a ground wheel 23 having a cushion tire J24. Thehub of the wheel 23 is indicated by the character 25 and is equipped with notches Y 26 toreceive a pin 21 carried bythe axle 22 so The agitator l3 includes a hub28 chambered to receive ananti-friction bearing 29 mounted on the sleeve and to prevent the marking ma.-

terial from getting into the anti-friction bearing suitable packing 30 is provided. The hub of the agitator rotates about the supporting sleeve 2i with a .r'ninin' umv amount of friction due to the arrangement of the'bearing 29 and is provided with a notch 3! to receive a. pin 32 carried by the axle 2 2. Thus it will be seen that the agitator has a connection with the axle 22 that'will bring about rotation of the agitator by the wheel 23. The end of the axle located outwardly of the a hopper has threaded thereon a nut 33 to permit wire and due to the shape of the grooves or slots can be easily removed and replaced when desired.

In operation, the hopper is filled with the marking material and the operator rolls the device over the ground by balancing the device on the wheel and the wheel rotating drives the agitator which keeps the marking material thoroughly agitated within the hopper so that it will flow evenly through the discharge slot and outwardly through the spout onto the ground in a line which provides on the ground a marking of the material.

when taken in connection with the drawings, will fully set forth the construction and advantages of this invention to those skilled in the art to which such device relates so that further detailed description will not be required. I

What is claimed is:

1. A line marker comprising a hopper having a said axle, an agitator journaled on the sleeve,

means for connecting the agitator to said axle,

l and a valve means in said spout.

2. A line marker comprising a hopper, a hearing sleeve carried by said hopper and arranged therein and opening outwardly through one wall thereof, an axle journaled in said sleeve and extending out of said hopper, a ground wheel secured on said axle, an agitator including a hub journaled on the sleeve, means for connecting the hub of the agitator to said axle, said hopper having a discharge slot located directly under the agitator, a spout carried by the hopper and underlying the discharge slot, a pivotally mounted gate in the-spout for controlling passing of material through the discharge slot and spout, and

, an operating means for said gate. It is believed that the foregoing description, H i

3. A line marker comprising a hopper, a bearing sleeve carried by said hopper and arranged therein and opening outwardly through one wall of said hopper, an axle journaled in said sleeve and extending out of said hopper, a ground wheel secured on said axle, a hub having a chamber to receive the sleeve, an anti-friction bearing on the sleeve within the chamber, packing means between walls of the chamber and theianti-friction bearing and one wall of the hopper, said hopper having a discharge slot located under the hub, tufts of bristles carried by said hub to c-oact therewith in forming an agitator, a spout carried by the hopper and underlying the discharge slot, said hub having a notch, and a pin extending through the axle and lying in the notch to establish a drive connection between said axle and the hub.
